ATA (PI) 80 pin Cable Detection
Set this option to select the method used to detect the ATA (PI) 80-pin cable. The SUNIT
and Fail-Safe setting is
Host & Device .
Option Description
Host & Device Set this value to use both the motherboard onboard IDE controller and IDE disk drive to detect
the type of IDE cable used. This is the default setting.
Host Set this value to use motherboard onboard IDE controller to detect the type of IDE cable used.
Device Set this value to use IDE disk drive to detect the type of IDE cable used.
The use of an 80-conductor ATA cable is mandatory for running Ultra ATA/66, Ultra
ATA/100 and Ultra ATA/133 IDE hard disk drives. The standard 40-conductor ATA
cable cannot handle the higher speeds.
80-conductor ATA cable is plug compatible with the standard 40-conductor ATA cable.
Because of this, the system must determine the presence of the correct cable. This
detection is achieved by having a break in one of the lines on the 80-conductor ATA
cable that is normally an unbroken connection in the standard 40-conductor ATA cable. It
is this break that is used to make this determination. The AMIBIOS can instruct the drive
to run at the correct speed for the cable type detected.
